rhombus or square if all angles are 90 deg
This is a parallelogram.
The opposite sides of a parallelogram are parallel lines and a parallelogram is a 4 sided quadrilateral
A TRAPEZIUM. Trapezia can be SYMMETRIC or ASSYMETRIC. That is Non-parallel sides can be of the same length or of different lengths/ intersext at different angles to the parallel lines.
Yes. A quadrilateral is any plane figure bounded by four straight lines. A rectangle is a quadrilateral with each of its vertex angles equal to 90°, opposite sides are parallel and of equal length but the pairs of opposite sides are of different lengths. A square is a rectangle with all its sides equal in length.
It is a trapezoid that has only one pair of opposite parallel lines of different lengths.
A trapezoid has exactly one pair of parallel lines
It is not possible to have a quadrilateral with four parallel sides - this would bea series of four parallel lines that do not intersect.A quadrilateral with four sides of equal length is a rhombus, however.And a quadrilateral with 2 pairs of parallel sides is a parallelogram.
The quadrilateral with 1 pair of opposite sides parallel is called a trapezoid.
A trapezium is a quadrilateral with two parallel lines.
A kite (if it's a quadrilateral).
A quadrilateral is any plane figure bounded by four straight lines. Within this definition are special shapes. The Parallelogram : has both pairs of opposite sides parallel (and opposite sides are equal in length). The Rhombus : is a parallelogram with all its sides of equal length. The Rectangle : is a parallelogram with each of its vertex angles equal to 90° (and opposite sides are of equal length). The Square : is a rectangle with all its sides of equal length. The Trapezium : is a quadrilateral with only one pair of parallel sides - which are NOT of equal length. The Isosceles Trapezium : is a trapezium with its two non parallel sides equal in length. The Kite : is a quadrilateral with two pairs of adjacent sides equal in length
If it has 2 pairs of parallel lines it is a parallelogram, if it is a quadrilateral. If there is not restrictions on the number of sides, then there are many answers
